Hydraulic Bolt Tensioner, 42 mm Bolt, M42 x 4.5, 65 mm A/F - Enerpac PGTS4265S

This hydraulic bolt tensioner preloads M42 x 4.5 bolts purely hydraulically, applying the clamping force without torque and without friction on the thread. The single-stage design delivers even, repeatable tension even on hard to reach flanges in wind, steam and gas turbines.

Benefits

• Even preload across multiple bolts with no friction losses, for secure flange joints
• Auto-retract piston speeds up the work cycle
• Zinc coating gives the puller lasting corrosion protection
• Interchangeable bridge and long-life seals for extended service intervals
• Mechanical over-stroke preventer protects the cylinder
• Quick-disconnect coupler for a safe, fast hydraulic connection

Applications

Designed for critical bolting in power generation, including wind, steam and gas turbines and flanges with limited access.
